Abstract

TÉCNICAS DE DETECÇÃO DE CANAL DE EQUIPAMENTO BASEADO EM QUADROS NO ESPECTRO NÃO LICENCIADO. A presente invenção se refere a métodos, circuitos e sistemas que são fornecidos para realizar detecção de canal de equipamento baseado em quadros no espectro não licenciado. Em um exemplo, um dispositivo de equipamento de usuário (UE) inclui um processador configurado para executar operações que incluem receber, de uma estação-base (BS), uma pluralidade de configurações de equipamento baseado em quadros (FBE) com tempo de ocupação de canal (COT) iniciado por UE; realizar a detecção do canal de FBE com COT iniciado por UE com base em uma configuração selecionada dentre a pluralidade recebida de configurações de FBE com COT iniciado por UE para obter um COT; e transmitir dados durante o COT.EQUIPMENT CHANNEL DETECTION TECHNIQUES BASED ON FRAMES IN THE UNLICENSED SPECTRUM. The present invention relates to methods, circuits and systems that are provided to perform frame-based equipment channel detection in unlicensed spectrum. In one example, a user equipment (UE) device includes a processor configured to perform operations that include receiving, from a base station (BS), a plurality of frame-based equipment (FBE) configurations with occupation time of channel (COT) initiated by UE; performing UE-initiated COT FBE channel detection based on a configuration selected from the received plurality of UE-initiated COT FBE configurations to obtain a COT; and transmit data during the COT.
